No it isn't. Its a general gauge of 6 pipes together. Each cyl can run 4points difference. Think about that. Heat signature on the earth strap,colour and condition on top of the body before the threads.Colouring on the porcelin. But reading em has to be done with new plugs and directly after a WOT pull with no idle time.

Its like the game guess who. Dose your diff have solid disks? Yes. Is your diff a EA/EB wagon diff? Flips down picture.

Those headers you have won’t even come close getting into an X series, been there and tried haha. If you can find the articles relating to Dick Johnson’s Pine Pac mustangs in the 80s they are a good read on how he managed to get 380hp from the asthmatic 302w back then.

if it has solid discs, it will be an E series diff(or XG) if it has vented discs that you cant remove without pulling an axle out it will be pre XD(XC and possible XB) if it has vented discs that can come off (one screw retains them) once the caliper is removed, and the caliper is Cast Iron, it will be XD diff. if it's got vented discs and alloy calipers, it will be XE or XF diff. that should be enough to id it. EB onwards series also have a round flange for the tailshaft to bolt on, where upto EA had the 2 straps over the uni joints.

There is a local factory Boss 302 is a street/circuit car has drag raced it a few times, Have thought a few times of getting my bros spare 5.0lt, basic reco with 230°ish cam, some Aeroflow alloy heads or AFD alloys, air gap or victor jr & maybe some nitrous... another idea was Aussie Speed Boss 302 hi rise to suit 2V Cleveland heads, & SRP BOSS 302 piston to suit Aussie 2v heads (302C closed chamber) 3.5cc dome, As for porting I brought a Makita 240V 1/4" die grinder (GD0600) & a long shank burr, heaps nicer then waiting on the compressor to try & keep up with my bluepoint die grinder.

I’ve seen some really cool builds on the net for the little Windsor, one liked the most was: Dart block 4.125 bore Steel 302 size crank Alloy Cleveland style heads etc Big roller cam Comes out at around 330ci Made just under 800hp on engine dyno. Wasn’t street friendly. Anyone know the bore and stroke and in a Ford 5.0 V8 supercar? I’m thinking the biggest bore possible around 4.185 and a stroke of 2.8 inch or similar???

last night i was trolling thru you tube and found a video on this rare boss 302 engine and assorted full factory race parts,very interesting video with so many nos parts in boxes ,like the CROSS BOSS intake,plus 8 autolite carby trumpet stacks.

302 Windsors post 86 have the same firing order as clevo, boss 302 uses clevo firing order as does 351 Windsor

Not that special nowadays...... 4 bolt mains, screw in welsh plugs, 7/16" rocker bolts etc. Can all be done in a machine shop, but, obviously without the bragging rights. Would be nice to own one, and sit it in the corner of the shed, and stare at it.

200 is definitely none too shabby, earlier Windsors I think were in the 150s, 351Ws maybe high 170s, 4V Clevos were up around 260. 2Vs aren't as good as you think, I believe Aussie castings were in the low 180s. US ones around 200. I think our casting methods and bowl work left much to be desired on our 2Vs. I reckon mine being very mildly ported puts them up around the 200 mark (of course not tested). I can see why GT40Ps were sought after in the day. Sort of like how Vortech heads are to Chev guys... Cheap, factory made upgrades. Sent from my CPH1903 using Tapatalk

From the factory they have 155cc intake and flow a tad under 200cfm at .500 lift through a small 1.85 intake valve. Which isn’t too bad really for a little factory Windsor considering a stock 2V Cleveland head flows the same. Sent from my iPhone using Tapatalk

The issue with the gt40p head is that it is good for about 300hp if you bang in a bigger cam and some compression. I did look into building up a set but bang for buck it wasn’t worth it and I went alloy. I have a real liking for the little 302 rollers. Sent from my iPhone using Tapatalk

Until you run out of money..!

The E303 is a good match for the GT40p heads and they run out of flow around .500 lift, not much point having a huge cam and restrictive heads. From memory the 40p head flows about 200cfm at .500 lift. Sent from my iPhone using Tapatalk

The E303 has a very nice choppy idle, very popular in the US, .498 lift and 220 degrees@.50 Yeah the factory springs aren’t much chop, but you would be fine running the E303, might get some valve float around 6k rpm. Sent from my iPhone using Tapatalk

If you're looking for decent street cams, the Ford Motorsport E303 and B303 are good, proven units that won't mess up the EFI. The B is a bit more cam than the E. Sent from my CPH1903 using Tapatalk

I ended up buying one of the Cube Speed shifters and a bronze bush. Did it through his ebay store, and due to discount voucher codes I saved about $25 and got free shipping.

i have time ,so i wanna buy a porting kit or something like that and match port the heads and maybe a bit more.

Most bottom end parts are cleaned ,block is ready to paint soon Sent from my SM-G570Y using Tapatalk

I’d look at putting bigger valves in, at least 1.9 intake and 1.6 exhaust. Sent from my iPhone using Tapatalk
